“A few times we had to delay for about five minutes for falconers to do inspections.”

Falconers are responsible for wildlife management at the airport. The falcons cause other species of birds to flee.

The delays were “minimal” and disruptions like this are rare, said Desgagnes.

The most spectacular example of a collision between an aircraft and birds was in 2009 when U.S. Airways Flight 1549 crash landed in New York City’s Hudson River after a flock of Canada Geese were sucked into the engines of the plane.
